Didn't go Trick or Treating, but did have a Marvel (movie) Universe party, and it went off well. Some random people that
were invited showed up
without costumes, stayed for like 20 minutes, and took quite a bit of pizza (which is kinda prick-ish. Show up late, leave early, no costume, eat up limited food), but other than that, it was pretty awesome.
It was way too cold for my mate's jacuzzi, but a lot of people went in, and had fun - Though were they chilly afterwards :v
People are calling for a DC Universe party next year, but we all spent quite a bit of money and time on THESE costumes, so we'll likely make it an annual Marvel party and just improve our costumes.
I was Captain America, the Host was Iron Man, his girlfriend was Black Widow, and then the rest goes - Thor, Dr. Octopus, Deadpool (Wolverine origins), Loki, Sandman, Magneto, and some dude who got the invite and proceeded to ignore the entire thing and came as
some random dude from Ranma 1/2.
